Re: Duplicate target error

From: TEMPLIE Cédric (cedric.templie_at_[hidden])

What can I do ? come back to use dependency, and duplicate linkflags to 
use the good library switch the variant ? Nevertheless, It does not 
remove the warning message about link incompatible....
Or there is a cleaner solution to avoid linkflags duplication switch the 
variant...

Thx again.
